Not an expert but it appears he may be getting MBD- medabodic bone disease
try giving him more calcium with feeding.
(listen to others that reply who have more experience with tokays though)
hope he is alright![]()
A uv light won't do any real good with a nocturnal animal. Make sure that the calcium that you are dusting it's food with contains D3 but NO phosphorus. It needs to have the D3. Also make sure that you're gut loading the feeder insects well. Your food is only as good as the food it eats. Also, its possible that it just partially broke its tail. In which case, there's not much you can do. Or, it could be a genetic tail kink...but in that case he would have had it when you got him.
Well, if it's a genetic kink, you wouldn't want to breed it. You don't want to pass on traits like kinked tails. If it's a broken tail there's nothing you can do really...just let it be. But if it's MBD, you should address the issue as it could lead to serious problems down the road.
my tokay's tail is just like that, but it has been that way since I got her (more than a year ago), so I don't see a real problem with that, good luck
